Memory Leak

Any more details?

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]) to this ticket.

This happens when I'm already in a world.When viewing the memory usage in task manager, Minecraft goes from ~500MB to 4GB + over ~20 seconds.
